This seems to affect only arrays of primitive type.
I modified Untitled20.java as follows:


/*

sample program:

*/
public class Untitled20 {

    public String xyz(char[] param) {
        return "abc";
    }

    public String xyz2(Object[] param) {
        return "def";
    }

    public static void main(String[] args) {
        char[] x = new char[20];
        Object[] y = new Object[20];
        Untitled20 xx = new Untitled20 ();

        String bb = xx.xyz(x);
        String cc = xx.xyz2(y);
        // add a line breakpoint on the next line:
        System.out.println(bb); /* stop at Untitled20:24
                                 * run
                                 * print xx.xyz2(y)
                                 * print xx.xyz(x)
                                 */
        System.out.println(cc);
    }
}


Once inside jdb and at a breakpoint on line 24, I evaluated
"print xx.xyz2(y)" 20 times with no error. Next I did a
"print xx.xyz(x)" and got the Signal 11 first time.
